Aipom, the Long Tail Pokemon

Monkeys are freaking awesome. Especially this one.

Fake Out
Double Hit
U-Turn
Acrobatics

EVs: 252 Attack, 252 Speed, 4 HP

Hold a Normal Gem, and have the Technician Ability. Observe Fake Out. This Attack is guaranteed to make the opponent flinch if it hits. Between the STAB, Technician, and the Normal Gem, Fake Out will deliver a blow of 180, AND make the target flinch, allowing you to deliver another attack without worrying about fainting beforehand. A Double Hit will do 2 hits of 61 power each, so that isn't bad. Acrobatics will have a power of 165 now that you are no longer holding the Normal Gem. U-Turn will only have 70 power, BUT it will switch you out, meaning you can use Fake Out again later in the battle. Keep in mind that Ambipom has a respectable Attack stat.

To get the little simian of destruction, just...

1) Breed a female Aipom with a male Smeargle that knows Double Hit, U-Turn, Acrobatics, and Fake Out.
2) Aim for the Run Away Ability(it will become Technician upon evolving) and an Adamant Nature.

Double Hit is really only there so Aipom can evolve at lv 2, after that, you're free to get rid of it for something else, perhaps Low Sweep or Covet. Just remember his purpose is to kill on the second turn. If you don't think you'll kill the target on the second turn, it is recommended that you use U-Turn in order to get out of there. Ideas and thoughts and so forth are always welcome.

Brock out.
